These worms are long, fiat and ribbon- like, nearly as thick near the lateral mar- gins as in the median line. The color shows considerable individual variation, but most specimens are dark, velvety brown above and flesh colored or creamy white below. Some are mot- tled, reddish brown or purple on the dorsal surface. Sometimes the head is almost without color. Ocelli very nu- merous, commonly numbering 60 or more on each side (PL 24, fig. 187). The worms often attain the length of a meter, and are about 5 mm. in width. The proboscis sheath reaches well toward the middle of the body, although the slender proboscis is but a fraction of this length. The armature of the proboscis includes a weak central stylet, the basis of which is swollen into a bulb posteriorly (PL 24, fig. 188; Text-fig. 33) and of a pair of pouches, each usi:- ally containing three small accessory stylets. There are 11 proboscidial nerves. Cerebral sense organs remark- ably large ; situated slightly in front of brain. Narrow intestinal caeca extend forward well toward brain. Submuscu-.
